Read-only System 3rd Time
Jun 11, 2009
I have brand new server with CentOS 5.3 and latest CentOS kernel (2.6.18-128.1.10.el5PAE).
I have brand new HDDs with no errors (HDDs have only 1000 power-on-hours, server CPU temperature is normal - between 35-42 C). My server went read-only without any reason. I need to fsck main / partition (/home is separated) and it cleaned journal, then server became online.
After 2 weeks it happens again - I did again fsck on / partition and it recovered journal as before. I decided to ask Data Center to replace RAID-1 card and memory - they did it. After 3 weeks server went read-only again.
I ssh into server and saw that kswapd0 process is using 100% cpu and load is over 170.
After fsck it recovered journal on / and server is again available.

I had a linux server (CentOs 5, mysql5, php5, directadmin). I had problems with apache few days ago, that's why i hire sys. admin who tweak the system (install the PAE kernel), and some more configurations, and during last 7-8 days server work w/o any downtime (before this server had 1-2 downtimes per day-> OOM killer.)
Now i had only ssh access (emails, directadmin access - give "wrong password" answer). As told my sys.admin It became read only system.
I cann't even reboot system
Quote:
[root@server sa]# reboot
reboot: /usr/local/lib/libpng12.so.0: no version information available (required by /usr/lib/libcairo.so.2)
such few commands work, the most commands that i know don't work
Quote:
[root@server ~]# ls -la
ls: error while loading shared libraries: libacl.so.1: cannot open shared object file: No such file or directory

I have a dedicated server and till few days back i was able to edit my files fine but this morning when i am trying to edit any file, it gives me back this error:
[user@domainname theme]$ chmod 777 header.php
chmod: changing permissions of `header.php': Read-only file system
[user@domainname theme]$
[root@domainname theme]$ chmod 777 directoryy
chmod: changing permissions of `directoryy': Read-only file system
[root@domainname theme]$
I tried both as normal user and root and same results. Do you think the hosting guys changed the permissions of the file system or something?

I want to take some data from a raid-disk (taken from a raid-1 sstem). Put it into a new system already, but this system doesn't have any raid.
When viewing "fdisk -l", it said /dev/sdb doesn't contain valid partition. Is there anyway I can mount it now? I am on CentOS 4 box

This is a rare issue i have on a RHEL 5.2 + cPanel server.
Server time is:
Tue Nov 11 17:02:51 CST 2008
Squirrelmail time show:
Code:
Last Refresh:
Tue, 5:02 pm
So, that is correct too..
But email arrives with -4 hours time, example:
webmaster@xxx.com 1:03 pm testing email
I already rebooted httpd, exim, and imap server, and the server itself too.. and problem stills.

I can't get access to a certain site. I always get the page with:
network time out - server at *** takes to long to respons. More people have noticed this and apparently it only happens to people with certain specific providers. And not all the time. Some times they DO get access eventy to they belong to the same ISP. So I guess an ISP isn't blocking access to it otherwise it would be permenantly/The site administrator insists that certain ISP's are blocking his site. He's hosting it on his own server. The domain belongs is registered at namecheap.com.
If an ISP is blocking this site (if that's possible?), that would lead to that 'network timeout' page wouldn't it?
What is the most likely reason for getting a timeout page anyway?

I have a dedicated server specs: AMD 3500+ 64 Bit CPU, 1 GB Ram, 160 GB Sata Drive. For 1 month, CPU load average reaches 40-50 value. This happens about 5-6 times in a day. When I stop httpd service for 30 seconds everything goes normal. I think this is not a DoS attack because it comes systematic, I dont believe no one makes this regularly except bots.
Maybe its a system service or a cronjob but it stops when I turn off httpd service?
How can I be sure about what's making this regularly load?
I also did set up a script which mail me when load average of system goes crazy and restart httpd service. But instant restart is not working to stop load increase.

The server is going down from time to time, every 12 days or so the site hosted there is no longer accesible, everything starts with the site slowing don and down and then is not longer reachable, what we do is to request a power cycle, and with this we start all over again till next power cycle, so on so on, of course, here are my server details and more info on this:
- MySQL - 5.1.41-3ubuntu12.10
- Apache - 2.2.14-5ubuntu8.4
- PHP - 5.3.2-1ubuntu4.9
- operating system: Ubuntu Server 10.04 LTS
After some time emailing the support guys to barely check about what's going on, we received an email with a few things:
1.- found a few errors that likely would cause issues with Apache. The first error is:
[Mon Feb 04 05:03:10 2013] [error] mod_fcgid: fcgid process manager died, restarting the server and the next error is:
[Mon Feb 04 14:32:34 2013] [error] server reached MaxClients setting, consider raising the MaxClients setting ...
Both these errors seem to indicate that you have a process that is running out of control on your server. We were unable to determine what script on your site is running caused your connections to be maxed out however it does appear that before these errors were generated there was a WordPress plugin referenced in your access logs...
2.- Additionally during our review we did find that your error log for mercadodedinerousa.com is 45 GB's which is excessively large and can cause problems when Apache is trying to write a such a large file.
3.- The majority of the errors being logged are:
[Wed Feb 06 12:12:31 2013] [error] [client 200.76.90.5] Options FollowSymLinks or SymLinksIfOwnerMatch is off which implies that RewriteRule directive is forbidden: /var/www/vhosts/mercadodedinerousa.com/httpdocs/index.pl, referer: [URL]

We have been working on a site for a while, couple of days ago I copied the source from the server - as there are few people making the changes to it - to get a fresh copy.
Yesterday I was blasted by my client that I have deleted files on the server and it had caused the site to go in disarray and they had to upload everything again.
I didn't delete anything, only copied, and after some arguments (naturally I am not happy with the allegation put on me) I was able to get the FTP log, but I don't really know how to read it, I am hoping that someone here would know and be able to assist:
HTML4Strict Code:
Tue Mar 04 16:49:29 2008 0 xx.xx.xx.xx 9365 /home/APP_NAME/public_html/user/add_room.php a _ i r xxxx ftp 1 * cTue Mar 04 18:20:02 2008 0 xx.xx.xx.xx 3909 /home/APP_NAME/public_html/About.php a _ o r xxxx ftp 1 * cTue Mar 04 18:20:04 2008 0 xx.xx.xx.xx 6046 /home/APP_NAME/public_html/affiliate-join.html a _ o r xxxx ftp 1 * cTue Mar 04 18:20:08 2008 0 xx.xx.xx.xx 6158 /home/APP_NAME/public_html/affiliate-join.php a _ o r xxxx ftp 1 * c
I have replaced the IP, application name with x.
I am guessing that *c means copy, but I don't want to make fool of myself when I confront them with this. Assuming that *c is copy what would be the command for delete?

I have a server with pacificrack. When I see my website it says "Read-Only File system" and my SSH dies with read-only file system errors.
It happens once per month, and the bad thing is I'm sleeping when it happens so I don't know my server is in this state.
Even though support fixes the problem within 15minutes of my support ticket, my server is down for hours because I don't know its down to then raise a ticket. I asked support why it happens and they never tell me... just tell me to read the logs but I'm not technical enough to understand linux logs etc.
Server is centos.

I received email from my cpanel server as follow:
IMPORTANT: Do not ignore this email.
This is cPanel stats runner on server.domain.com! While processing the log files for user xxxx, the cpu has been maxed out for more than a 6 hour period. The current load/uptime line on the server at the time of this email is 18:46:25 up 59 days, 13:16, 0 users, load average: 2.24, 2.23, 2.25
You should check the server to see why the load is so high and take
steps to lower the load. If you want stats to continue to run even with a high load
So what does this mean? and how can i check out this? how to reduce the cpu usage? Where to see the current usage?

Somehow the filesystem on my server turned read-only. The databases would not connect. When I rebooted the box it would not come up.
Support had to run FSCK. Even after, the databases had to be repaired using the CPanel tool. Things seem to be ok now, however:
1. What could have caused this to happen? Software or hardware failure?
2. I get these notifications, should I be worried?

About a month ago, I searched desperately for days to host my social networking site and file hosting site. Thankfully I found Wiredtree(WT) to be suitable for my budget. I signed with them with their entry plan of $44.10 and was happy with their service. The customer support was extremely helpful and they did everything to make my life better.
Nevertheless my project didn't turn up as expected and I decided to close the hosting.
Just a day before the end of one month of hosting, I wrote to them asking to close the account and also congratulating their service I also told them I would look forward to host with them in future and would recommend them. I expected a warm termination without any hassle. But i got a mail quoting their TOS (which says I should inform them 7 days in advance) and asking me to pay up another month's hosting fee before I can close the account. Along with it was a note from the staff to use the client portal to contact Billing Department directly to close the account (hmmm would they ask me to contact sales department directly if I tell me I want to add new server?). What hurt me was not the extra $44.10 which I will pay them anyway, but what they could have done was to understand my genuine case(first time customer). Tell me, how many of us read the TOS really. I requested them not to charge me, but got same cold response asking me to adhere to the TOS.
On the other hand my experience with other host (PM me if you want to know who) was one of awe and amazement. I wrote asking them the price I should pay to have more bandwidth. To my surprise I got extra bandwidth absolutely free though it wasn't mentioned such things in their TOS.
Well I learned a lesson today not to forget the importance of TOS and i am sure new webmasters will find this post useful.
This thread is not against the WT service. But a warning to new webmasters who might miss the fine print.

I just thought I would riase an issue you with you about the following host:
hostvector.com
hostmds.com
The reason:
I have received a number of e-mails over the last 2weeks that look like they are from my bank asking me to log-in and update my security information. I no my bank doe's not ever do this so I contacted them. When sending on the mail to them, they where able to trace the e-mail and it took them back to the address listed above using the e-mail account psychic@sabre.hostvector.com.
So before you hand over your bank account details to them I highly recommend that think twice.

I'd love to contact the domain registrars of the recipient spammers who are barraging me with the latest "google riches", or "ebay success" sales pitch emails, but I lack the knowledge of how to reveal the email headers and interpret them.
Is there a particular email client program that would allow me to view all parts of the email ? Maybe I'm using the wrong client (outlook), that would not allow me to view the more technical parts of the email, but but I don't know.
If I go ahead and click on their "unsub me" links at their bottom, that's their tricky way of finding out what emails are active and possibly make it worse for me. I know that it's illegal to send me email that I didn't opt into, in the first place, even if they do provide the unsubscribe link at the bottom, with the usual "Icann" spam disclaimer that they include.

I have a server with 2 hard drives.
1. I configured the onboard Raid 1, both as Volume0
I installed CentOS successfully. So I tested the RAID to see if the mirror really works
2. I took out hddA and boot hddB as single drive. it work!
3. Then I took out hddB and boot hddA as single drive. it work!
4. Then I plug back hddA & hddB back together & boot it up
It gives me many error screen, I had to login as repair screen with root password. It says everything is read-only. So I try to remount but it fails
#e2fsck -y /dev/sda1
#mount -t ext2 -o rw,remount /dev/sda1 /
#mount -n -o remount ext2 /dev/sda1 /
#mount -o remount,rw /
None above works. I wonder if I am not suppose to do that way the first place?

It there any good way to stop using from reading /etc/passwd?
I have suPHP enabled and open_basedir enabled by WHM too. But it seems susphp ignores open_basedir restrictions?
Here is virtual host config:
<VirtualHost x.x.x.x:80>
<IfModule concurrent_php.c>
php4_admin_value open_basedir "/home/xxx/:/usr/lib/php:/usr/php4/lib/php:/usr/local/lib/php:/usr/local/php4/lib/p$
php5_admin_value open_basedir "/home/xxx/:/usr/lib/php:/usr/local/lib/php:/tmp"
</IfModule>
<IfModule !concurrent_php.c>
<IfModule mod_php4.c>
php_admin_value open_basedir "/home/xxx/:/usr/lib/php:/usr/php4/lib/php:/usr/local/lib/php:/usr/local/php4/li$
</IfModule>
<IfModule mod_php5.c>
php_admin_value open_basedir "/home/xxx/:/usr/lib/php:/usr/local/lib/php:/tmp"
</IfModule>
<IfModule sapi_apache2.c>
php_admin_value open_basedir "/home/xxx/:/usr/lib/php:/usr/php4/lib/php:/usr/local/lib/php:/usr/local/php4/li$
</IfModule>
</IfModule>

# To customize this VirtualHost use an include file at the following location
# Include "/usr/local/apache/conf/userdata/std/2/xxx/xxx.com/*.conf"
</VirtualHost>
Scripts are running with user's UID, and that is fine, but it can still read /etc/passwd file for example.
How to fix that? Is it really open_basedir value is ignored by susphp? It works fine if I remove suphp and run scripts with nobody uid.
